In a sprawling city where shadows come to life, you play as Alex, a down-on-their-luck private investigator with a knack for uncovering the truth. After receiving a mysterious call to investigate a series of bizarre shadow-related incidents, you soon realize that these shadows aren’t just tricks of light; they have their own stories and desires. Each shadow represents a different character with a unique backstory, and as you interact with them, you'll unveil a deeper conspiracy that connects the living and the spectral. Navigate moral dilemmas, form alliances with reluctant shadow allies, and piece together the mystery before the shadows' secrets become a danger to both realms. With multiple endings based on your choices, 'Whose Shadow Is That?' challenges you to reflect on identity, truth, and the nature of reality itself.
